I don't think dojos necessaryily "provide" especially if their not AUSKF affiliated or directly affiliated with that club. It is more of a labor of love and a college club is a very different animal than a dojo. Especially when you have students working together although some older clubs like Harvard, Rutgers and Cornell have the system down and even though people graduate the clubs remain productive (recruiting people, hosting tournaments, running the club).
Stroud-sensei that list is somewhat helpful but would miss alot of college clubs. Not all college clubs are AUSKF affiliated and you never know when visiting students from Japan or students with previous experience come to a college and start a club. Maintaining the minimum number of members are having people members of different federations doesn't make it easy for all clubs. In that since I think if there was some mechanism to allow people at University clubs who were non-AUSKF members to join either through a neighboring AUSKF dojo or one close to their home. That AUSKF membership would increase plus you wouldn't have Joe Blow who has been a mudansha despite 4 years of college kendo winning every tournament. There wourld be more motivation for them to test and take advantage of AUSKF events.
